the problem you're seeing appears also if you use "import web.one"
or "from web import one" or "__import__('web.one')".

I think, but I'm not 100% sure, that the problem you're seeing is
that Python hasn't finished importing the "web.one" module when
you're trying to import it again.
- testimport wants to import web.one
- python imports the web module
- python finishes importing the web module
- python imports the web.one module
- web.one wants to import web.two
- python imports the web.two module
- web.two wants to import web.one
- python notices that web.one is already being imported, and
leaves it to the original import to finish the task
if you replace the "from web import" statements with plain imports,
everything will work as expected. just change
from web import one
to
import one
and do the same for the other module.
hope this helps!
